RESUMO

BACKGROUND: While the use of antibiotic prophylaxis is clearly advantageous to prevent streptococcal infection, it alters the composition of the gut microbiota in mothers and infants. Enterococcus faecium L3 is one of the best studied probiotic strains and shows strong antagonistic activity against Streptococcus agalactiae due to the production of bacteriocins able to inhibit common gut and vaginal pathogens. METHODS: We tested an L3-based probiotic formula (iNatal®) on 127 pregnant women attending our gynaecological unit in 2015. We compared the study subjects with 279 pregnant women enrolled in the same year and with 892 other pregnant women who attended our gynaecological unit in 2013 and 2014. RESULTS: The findings demonstrate: (a) the safety profile of the product; (b) its ability to reduce gut disorders; (c) a 6% decrease in the incidence of streptococcal colonization; (d) an approximately 30% decline in episodes of premature rupture of membranes; (e) fewer caesarean sections during labour; and (f) a reduction in pathological umbilical cord blood pH. CONCLUSIONS: Our results demonstrate that a probiotic treatment during pregnancy could have unexpected but favourable clinical results. Further randomized, double-blind, placebo controlled studies are now needed to confirm our preliminary findings.

RESUMO

PURPOSE: Sexual and urinary dysfunctions are complications in radical treatment of deep infiltrating endometriosis (DIE) with colorectal involvement. The aim of this article is to report the preliminary results of our single-institution experience with robotic treatment of DIE, evaluating intraoperative and postoperative surgical outcomes and focusing on the impact of this surgical approach on autonomic functions such as urogenital preservation and sexual well-being. METHODS: From January 2011 through December 2013, a case series of 10 patients underwent robotic radical treatment of DIE with colorectal resection using the da Vinci System. Surgical data were evaluated, together with perioperative urinary and sexual function as assessed by means of self-administered validated questionnaires. RESULTS: None of the patients reported significant postoperative complications. Questionnaires concerning sexual well-being, urinary function, and impact of symptoms on quality of life demonstrated a slight worsening of all parameters 1 month after surgery, while data were comparable to the preoperative period 1 year after surgery. Dyspareunia was the only exception, as it was significantly improved 12 months after surgery. CONCLUSIONS: Robot-assisted surgery seems to be advantageous in highly complicated procedures where extensive dissection and proper anatomy re-establishment is required, as in DIE with colorectal involvement. Our preliminary results show that robot-assisted surgery could be associated with a low risk of complications and provide good preservation of urinary function and sexual well-being.

RESUMO

CONTEXT: The proximate cause of functional hypothalamic amenorrhea (FHA) is reduced GnRH drive. The concomitant increase in circulating cortisol suggests that psychogenic stress plays an etiologic role, but others have argued for a strictly metabolic cause, such as undernutrition or excessive exercise. Indeed, our finding that the cerebrospinal fluid (CSF) concentration of CRH was not elevated in FHA cast doubt about the extent of hypothalamic-pituitary-adrenal activation in FHA and, therefore, we wondered whether central cortisol levels were elevated. OBJECTIVE: We tested the null hypothesis that CSF cortisol levels would be comparable in FHA and eumenorrheic women (EW). DESIGN: The study is a cross-sectional comparison. SETTING: The study was set in a general clinical research center at an academic medical center. PARTICIPANTS: Fifteen women with FHA who were of normal body weight and 14 EW participated. INTERVENTION: Blood samples were collected at 15-min intervals for 24 h, followed by procurement of 25 ml CSF. MAIN OUTCOME MEASURES: Cortisol, cortisol-binding globulin (CBG), and SHBG levels in blood and CSF were the main outcome measures. RESULTS: CSF cortisol concentrations were 30% greater when serum cortisol was 16% higher in FHA compared with EW. Circulating CBG, but not SHBG, was increased in FHA and, thus, the circulating free cortisol index was similar in FHA and EW. Because CBG and SHBG were nil in CSF, the increase in CSF cortisol in FHA was unbound. CONCLUSIONS: The hypothalamic-pituitary-adrenal axis is activated in FHA. The maintenance of CRH drive despite increased CSF cortisol indicates resistance to cortisol feedback inhibition. The mechanisms mediating feedback resistance likely involve altered hippocampal corticosteroid reception and serotonergic and GABAergic neuromodulation.

RESUMO

OBJECTIVE: To investigate, in a randomized clinical study, the efficacy of an isopropanolic aqueous extract of Cimicifuga racemosa (CR) on climacteric complaints in comparison with low-dose transdermal estradiol (TTSE2). Hormonal parameters, lipid profile and endometrial thickness were also evaluated. METHODS: Sixty-four postmenopausal women were enrolled and over the course of 3 months filled in a diary recording the number of hot flushes per day. Other climacteric symptoms (vasomotor and urogenital symptoms) as well as anxiety and depression, were evaluated at baseline and after 3 months. Gonadotropins (follicle-stimulating hormone (FSH), luetinizing hormone (LH)), prolactin (PRL), 17 beta-estradiol (17beta-E2) and cortisol, lipid profile (total cholesterol high-density lipoprotein (HDL)/low-density lipoprotein (LDL)-cholesterol, triglycerides, liver function (glutamic-oxalacetic transaminase, glutamic-pyruvic transaminase) and endometrial thickness were measured. Patients were randomly allocated to receive, for 3 months, either 40 mg isopropanolic aqueous CR extract daily or 25 microg TTSE2 every 7 days plus dihydrogesterone 10 mg/day for the last 12 days of the 3-month estradiol treatment. RESULTS: Both CR and low-dose TTSE2 significantly reduced the number of hot flushes per day (p < 0.001) and vasomotor symptoms (p < 0.001), starting at the first month of treatment. Such a positive effect was maintained throughout the 3 months of observation, without any significant difference between the two treatments. An identical effect was evident also for both anxiety (p < 0.001) and depression (p < 0.001) which were significantly reduced following 3 months of both CR and low-dose TTSE2. Total cholesterol was unchanged by CR treatment but significantly (p < 0.033) reduced by 3 months of low-dose TTSE2. A slight but significant increase of HDL-cholesterol (p < 0.04) was found only in women treated with CR, while LDL-cholesterol levels were significantly lowered by 3 months of both CR (p < 0.003) and low dose TTSE2 (p < 0.002). Triglycerides were not affected by both treatments, nor was liver function. FSH, LH and cortisol were not significantly affected after the 3-month treatment, while PRL (p < 0.005) and 17 beta-E2 (p < 0.001) were increased slightly only by low-dose TTSE2. Endometrial thickness was not affected by either CR or low-dose TTSE2. CONCLUSIONS: CR (40 mg/day) may be a valid alternative to low-dose TTSE2 in the management of climacteric complaints in those women who cannot be treated with or just refuse conventional strategies.

RESUMO

OBJECTIVE: The dose-effect relationship of nifuratel (CAS 4936-47-4) + nystatin (CAS 1400-61-9, CAS 34786-70-4) (Macmiror Complex) in topical treatment of vulvo-vaginitis was studied. METHOD: Sixty patients with Trichomoniasis and/or Candidiasis were randomized to: 1) nifuratel 125 mg/nystatin 50000 IU, 2) nifuratel 250 mg/nystatin 100000 IU, 3) nifuratel 500 mg/nystatin 200000 IU. Undistinguishable ovules were intravaginally applied qd for 10 days. The dose-effect relationship was assessed by ANCOVA. RESULT: After 5 days the microbiological cure rate occurred in 10% of patients in the least dose, in 40% in the middle dose and in 85% in the highest dose group (P = 0.000). After 10 days of treatment, the microbiological cure rate increased to 45%, 84%, and 95%, respectively (P = 0.007). Clinical signs and symptoms gradually disappeared in a dose- and time-dependent manner. No relapse has been observed after 10 day-follow up on 46 patients. CONCLUSION: The results confirmed a linear relationship between nifuratel + nystatin dose and effect. The least effective dose was nifuratel 250 mg + nystatin 100,000 IU once daily for 5 days and the best dose in terms of risk/benefit ratio was nifuratel 500 mg + nystatin 200,000 IU once daily for 5 days.

RESUMO

To assess the neuroendocrine correlates of menstrual status migrainosus (MSM) and menstrual migraine (MM), we evaluated the prolactin (PRL) and cortisol responses to the direct central serotoninergic (5-HT) agonist meta-chlorophenylpiperazine (m-CPP) administered orally (0.5 mg/kg) during the follicular (FP: +6, +8) and luteal phases (LP: -4, -6) of the same menstrual cycle. Ten women with MSM (migraine attacks occurring within 2 days of the onset of menstrual bleeding but lasting more than 72 h) and 9 women with MM (migraine occurring within 2 days of the onset of menstrual bleeding with a typical duration of attacks) were studied. Six healthy women served as controls. Blood samples were taken at times -30, 0 and every 30 min over 4 h. Statistical analysis was performed using MANOVA followed by Duncan's post hoc comparisons. We found that the PRL response to the m-CPP test was significantly blunted in MSM compared with MM and controls in both phases of the menstrual cycle (F = 4.6; p < 0.001). Indeed, the PRL area under the curve (AUC) after m-CPP was higher in both MM and controls compared with MSM (F = 12.7; p < 0.001). The m-CPP-induced cortisol response was absent in MSM compared with MM and controls in both FP and LP (F = 4.1; p < 0.001). On the other hand, the pattern of the plasma cortisol response to m-CPP was similar in MM and controls throughout the menstrual cycle. In addition, the basal plasma cortisol levels were significantly higher in MSM compared with controls (p < 0.001) and MM (p < 0.001) during FP, but not in LP, and progressively decreased over time. Thus, no significant effect of the menstrual cycle phase and diagnosis on the cortisol AUC was found, while a significant diagnosis effect (F = 25.6; p < 0.001) on %delta(max) plasma cortisol levels was evident and consistent with the lack of cortisol response to m-CPP in MSM during the FP and LP compared with MM and controls. A derangement in central 5-HT control of pituitary PRL, and even more so in cortisol release, is present in women with MSM, but not with MM, regardless of the phase of the menstrual cycle, suggesting the involvement of some 5-HT(1) and 5-HT(2) receptor subtypes in the occurrence of extremely severe migraine attacks triggered by menstruation.
